Furthermore, analysing the spatial correlation of these anomalies is of fundamental importance for obtaining a correct archaeological interpretation. In this work, we analysed the main results of electrical resistivity tomography (ERT), ground-penetrating radar (GPR) and magnetic gradiometry methods in a particular area of the archaeological site. In this analysis, we performed graphical and numerical spatial correlation analyses of the anomalies and observed strong agreement among the results provided by each method. Certain anomalies were reflected only in the magnetic and ERT studies. The results highlight the importance of applying several geophysical methods and performing spatial correlational analyses. Furthermore, the methodology that we have applied to evaluate the spatial correlation offers interesting results.<\/jats:p>","DOI":"10.3390\/rs12121989","type":"journal-article","created":{"date-parts":[[2020,6,23]],"date-time":"2020-06-23T09:05:33Z","timestamp":1592903133000},"page":"1989","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Exploring the Consistency of Data Collected in Archaeological Geophysics: A Case Study from the Iron Age Hillfort of Villasviejas del Tamuja (Extremadura, Spain)"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8377-0972","authenticated-orcid":false,"given":"Carmen","family":"Pro","sequence":"first","affiliation":[{"name":"Centro Universitario de M\u00e9rida, Universidad de Extremadura, 06800 M\u00e9rida, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4745-6972","authenticated-orcid":false,"given":"Bento","family":"Caldeira","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica da Escola de Ci\u00eancias e Tecnologia, Instituto de Ci\u00eancias da Terra (ICT), Universidade de \u00c9vora, 7002-554 \u00c9vora, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8202-1782","authenticated-orcid":false,"given":"Maria Teresa","family":"de Tena","sequence":"additional","affiliation":[{"name":"Centro Universitario de M\u00e9rida, Universidad de Extremadura, 06800 M\u00e9rida, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Charro","sequence":"additional","affiliation":[{"name":"GPEX-Junta de Extremadura, 06800 M\u00e9rida, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4114-7570","authenticated-orcid":false,"given":"Rui Jorge","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica da Escola de Ci\u00eancias e Tecnologia, Instituto de Ci\u00eancias da Terra (ICT), Universidade de \u00c9vora, 7002-554 \u00c9vora, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Fernando","family":"Borges","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica da Escola de Ci\u00eancias e Tecnologia, Instituto de Ci\u00eancias da Terra (ICT), Universidade de \u00c9vora, 7002-554 \u00c9vora, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victorino","family":"Mayoral","sequence":"additional","affiliation":[{"name":"Instituto de Arqueolog\u00eda (CSIC-Junta de Extremadura), 06800 M\u00e9rida, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,20]]},"reference":[{"key":"ref_1","unstructured":"Dallmeyer, R.D., and Mart\u00ednez Garc\u00eda, E.
